13 Claims. (01. 22017) This invention relates to improvements insanitary waste cans or garbage receptacles of the type including anouter can body or frame having a swinging cover and an inner can body orpail having a handle.

It is the chief object of this invention to provide simple andinexpensive means for coupling the inner pail to the outer pail andthereby permit the carrying of both the inner and outer canbodies as aunit by the one handle, when desired.

Another object is the provision of a coupling means of this characterwhich is positive and reliable in operation, and which is designed to beconveniently controlled.

A still further object of the invention is to provide a novel andefficient automatic coupling mechanism which is designed to be latchedwhen the cover of the outer can-body is closed to prevent the withdrawalof the inner can-body from the outer one, and which is released when thecover is opened to permit of such withdrawal.

In the accompanying drawings:

Figure 1 is a side elevation, partly in section, of a receptacleembodying my improvements. Figure 2 is a side elevation thereof showingthe cover elevated, the coupling member being released, and the innerpail partially withdrawn from the outer can-body. Figure 3 is anenlarged fragmentary vertical section taken substantially in the planeof line 3-3, Figure 1. Figure 4 is a fragmentary side elevation, on anenlarged scale, of the coupling member or yoke, the same being shown byfull lines in its released position and by dotted lines in its latchedor coupled position. Figure 5 is a fragmentary section taken "on line55, Figure 3. Figure 6 is a ,view similar to Figure 4, showing aslightly modified formof the coupling member; Figure '7 'is a sideelevation, partly in section, showing a modification of my invention.Figure 8 is a side elevation, similar to Figure 2, of such modification.Figure 9 is an enlarged fragmentary vertical section on line 99, Figure'1. Figure 10 is a fragmentary side elevation, on an enlarged scale, ofthe coupling member or hook, the same being shown by full lines in itslatched position, and by dotted lines in its released position. Figure11 is a view similar to Figure 10, showing aslightly modified form ofthe coupling member or hook.

Similar characters of reference indicate corresponding parts throughoutthe several'v'iews.

In the preferred embodiment of the invention shown in Figures 1-6,inclusive, the same comprises an outer can-body, supporting frame orcontainer 10 of cylindrical form, open at its upper end and made ofsheet metal or, other appropriate material. Removably contained withinthis can body is a garbage can or receptacle 11 having a bail or handle12 pivoted thereto adjacent its upper end. As seen in Figure 3, thisbail is connected to radial pivot pins 13 projecting from diametricallyopposite sides of the pail 11 and being-of a length to extend beyond thewalls of the outer can-body 10.

The upper end of -the can body 10 is provided with a vertically swingingcover 14 pivotally connectedby a strap 15 with a bracket 16 secured to Ithe rear side of said can-body. The means for raising the cover to itsopen position may be of any suitable construction, that shown in thedrawings consisting of a substantially horizontal rock shaft 1'? locatedat the lower end of the outer can-body and terminating at its front endin a foot pedal 18 and at its rear end in a crank arm 19' connected by alink 20 with the cover-strap 15. When the foot pedal is depressed, therock shaft is oscillated in a direction to cause its crank to pulldownwardly on the link 20 and open the cover, as seen by dotted lines inFigure 1. With the cover in its open position, the inner pail 11 can bereadily removed from the outer can-body by swinging thehandle 12 to theupright position shown in Figure 2.

In order to permit of conveniently carrying both the outer can-body l0and-the inner pail 11 as a unit by the handle 12, I have provided acoupling mechanism for enabling the waste can to be so carried or forpermitting the inner pail to be readily uncoupled from the outercan-body and be independently removed therefrom, as when it is desiredto empty the contents of the inner pail into an outdoor receptacle orother place to receive it. To this end, I provide the upper end of theouter can-body 10 in its diametrically opposite sides withupwardly-opening notches or recesses 21, which are adapted to receivethe handle-pins 13 in the lowered position of the inner pail, as shownin' Figures 1, 3 and 4. In this connection it will be noted that thehandle 12 is connected at its free ends to' the outer end of the pins 13and in its lowered position, shown by full lines in Figure 1, the handlepartially embraces the front side of the outer can-body 10. For thepurpose of arresting the downwardswinging movement of the handle andpreventing its striking against the outer can body and marring itsfinish, the handle-pins preferably terminate at their outer ends insubstantially vertiGa/l eyes 13a and the perforated ends of the handlesare threaded on the top portions of the eyes while the lower portionsthereof constitute stops or abutments against which the adjoining edgesof the handle are adapted to engage in the lowered position of thehandle, as shown in Figures 1 and 5.

Mounted on the opposite sides of the outer can-body 10 adjacent itsrecesses 21, are coupling members or catches 22 which are preferably ofyoke shape and are pivoted at 23 to swing vertically. Each yoke-shapedcoupling member terminates at one end in a hook 24 which is adapted tointerlock with the top side of the companion handle-pin 13 to preventits displacement from the companion recess 21, .whileits-opposite endterminates in a trip arm 25 for shifting the yoke to its coupled orlatched position as shown by full lines in Figure l and by dotted linesin Figure 4. A spring 26 connected at one end to the yoke 22 and at itsother end to the can-body 10 serves to constantly urge said yoke to itsreleased position shown by full lines in Figures 2'and 4, in whichposition the space or recess 27 formed between the yoke elements 24 and25 registers with the companion recess 21 in the can-body to permit thewithdrawal of'the inner pail therefrom.

The trip arm 25 of the coupling member 22 is so disposed that it isengaged by the rim of the cover 14 in its closed position to maintainthe coupling yoke in its latched position'to prevent withdrawal of theinner pail from the outer one and thereby permit both can-bodies to becarried as a unit from the one handle. When the cover is raised, thespring 26 swings the coupling member toits released position to uncouplethe inner pail from the outer pail and permit its removal therefrom, andwhen the cover is again closed the coupling member is automaticallytripped to its latched position, the weight of the cover holding it insuch position.

In the modified form of the coupling member shown in Figure 5, the sameis provided with a weighted arm 28 which serves constantly to swing thecoupling member to its released position. In both forms of theinvention, a stop pin 29 is employed for limiting the swinging movementof the coupling member to such released position.

In the modified form of the invention shown in Figures 6-10, inclusive,wherein the elements of the waste receptacle have been given the samereference characters as for the previously described construction, thecoupling member is in the form of a vertically-swinging lever or catch30 pivoted at 31 to the can-body l0 and terminating at its upper end ina hook 32 which is adapted to interlock with the companion handlepin 13.A spring 33 applied to the-catch serves to constantly urge it to itslatched position, while a stop 34 limits the swinging movement of thecatch to its released position. At its sides these catches may beprovided with laterally-bent flanges 35by which they may be shifted bythe user to their released positions when it is desired to remove theinner pail 11 from the outer can-body 10. If desired, however, thesecatches may be released by swinging the handle 12 rearwardly to bringtheir lower ends into engagement with the flanges 35 and thereby eifectthe release of the catches from the handle-pins 13, at the same timeraising the inner pail with the handle I as a lever until thehandle-pins are clear of. the

catch, after which the inner pail can be removed in an obvious manner. I

In the modified form of the catch shown'in Figure 10, the same isprovided with a weight 36 to urge it to a latched position.
